Warning tape shall be set at 0.3-0.5m above the top of buried gas pipeline. Its functions are:

1. During excavation, if a warning tape is found, it means that there is a gas pipeline 0.3 to 0.5m below, which serves as a warning and protection.

2. Tracing effect. When searching for buried gas pipeline, find the warning tape and find the pipeline. It plays a tracer role.

3. Now the warning has a trace line, and the test instrument can accurately position the pipeline without excavation.

No excavation is allowed if there are cables underneath; If there is a water supply pipeline under it, excavation is strictly prohibited; It is forbidden to excavate if there is a gas pipeline under it; If there is an oil pipeline under it, excavation is strictly prohibited.
